Specification of Letters Patent.

Patented March 9, 1909.

Application filed January 22, 1907. Serial No, 358,581.

To all whom it may concern:

Be it known that I, REGINALD B. CALCU'IT,

a citizen of the United States, and resident use.

meke the colledwire endless, its ends are of Austin, Cook county, Illinois, have i11- vented certain new and useful Improvements. in Tires for Vehicles, of which the following is a'fu ll, clear, and exact description.

My invention relates to tires for vehicles, and particularly to the tires of li ht vehicles such as bab 'carria es, velocipeiles, etc.

Tires ma e of coi ed wire have for a long "time past been tho'ught of, but have not,

to my knowledge, been'put into practical This, probably, is, to a greater or less extent, due to the fact that, in order to secured together by a coupling device,

' soldering the ends of the spirally coiled ire of the tire to ether.

which, to the extent of its length, nade the .tire solid and without resiliency, and caused the Wheel, as this portion of the tire relied over the round to "bump, or, in other words, to e unyieldmg, as compared to the resiliency of the remainder of the circumference of the tire. I

The ob ect of my invention IS to overcome this ObJeCtlOH entlrely, and 1t consists in 'dis ensmg, except as a possible incident,

wit any coupling or filler in the bore of the coi ed Wire tire altogether. "This I accomplish y the means hereinafter fully described, and as particularly pointed out in the claims.

In the drawings: F igurel is a side view of a segment of a spirally coiled ire tire In Fig. l the ends, A and A, are )evcled, and are brought together and ovcr-lapped,,so that, as near as possible, their axcsaline, preferably, at the side of the tire, as shown, or at the. inner circumference. The point where the ends are brou ht together is, preferably, located as stator because the ends would be less.

subject to movement there, and consequently would be less liable to be forced apart or separate than if located within tlfe area offthe tread of the tire. k In Fig. 2 of the drawings the endsfB of the Wire are given an undercut bevel, or bevel the reverse of that shot n in Fig. l, and then overla pod and welded or soldered together, and in Fig. 3 of the drau in s the ends U of the wire cut off transverse welded or soldered together. Vhen the ends are welded together the metal of the ends are made homo eneous, but i. hen brazed or soldered, the hart or soft solder is, preferably, made to collect around the joint b forcing apart the coils of u ire next the cndis n ith some suitable instrument and applying the solder so as to surround the same. When doing this thesolder aftcrjt gets on the inside of the tire is hard to control, so I and B and butt prefer to use, what I call a "matrix" 1), consisting of a pin of slightly less diameter than the bore of t 1e tire and of a lcngth just enough to back the joint, and insert it in the bore of the ends at the time they are brought together, and then pour in the solder. The matrix causes the solder to spread and completes the joint nithout causing a solid tire portion, and causing the Wheel to bump, because its diameter docs not prevent the ielding of the lrcad and cousi quent resi iency.

What I claim as new is:

l. A tire for vehicles com n'ising a spirally coiled uire having a closed bore thecnds of which are brought together, a m'ctal matrix of lcss diameter than said bore inserted in the bores of the ends of said coilcd wire,and a la. er of fusible metalunililn said matrix to tie notion of the coil adpu wnt to the tread si e.

2. A tire for heels comprising a sp rally coiled ire having a closed bore lhc ends of \ahich are brought together, and a metal matrix of less diameter than said borc which has a portion of its exterior fusible by heat and is inserted in the bores of the ends of said coiled u ire and binds the same together.

.In testimony hereof I have hereunto set 'my hand and Send this 14th day of January.
